AWNING TYPE WINDOW STRUCTURE WITH LOCKING MEANS Filed Dec. 9, 1959 3 Sheets-Sheet 3 ATTORNE Y United States Patent "ce 3,045,296 AWNING TYPE WINDQW STRUCTURE WITH LUCG MEANS Arthur Silverman, 55 Harrison Drive, Short Hills, NJ. Filed Dec. 9, 1959, Ser. No. 853,518 4 Claims. (Cl. 20-42) This invention relates to window structures and more particularly to such of the awning type with manually operating means and a latch or hook lever which auto matically locks the window sash as it is closed and unlocks it prior to being opened.

Windows of the awning type are in use in which means are provided for opening and closing the sash, either singly or in unison, together with means for thereafter locking them tightly closed. One disadvantage of this construction is not only the dual operation required but the fact that the locking means may be in locked position when it is attempted to close the window sash or may be inadvertently unlocked after the window sash is closed.

One object of the invention is to provide novel and improved means whereby upon operation of the window opening mechanism, a window latch or locking means is first disengaged from the window to allow the latter to open and as the final step, the latch or locking means is again actuated after closing of the window to lock the window in closed position.

Another object is to provide an awning type window of this character with means for opening and closing one or more of the sash or vents of such a window, in combination with mechanism simultaneously and automatically operated by the opening and closing means so that before the window opens it is first unlocked and after the window closes it is locked.

Another object of my invention is the provision of mechanism for operating awning type windows of the above construction which is easily manufactured and whose parts are readily replaceable.

A further object of my invention is to produce a window structure comprising means for operating the sash thereof and means interlocked with said operating means for automatically locking said sash at it is closed and unlocking as it is opened.

These and other objects and advantages will become apparent from the following detailed description when taken with the accompanying drawings. It will be understood that the drawings are for purposes of illustration and do not define the scope or limits of the invention, reference being had for the latter purpose to the appended claims.

In the drawings, wherein like reference characters denote like parts in the several views:

FIGURE 1 is a perspective view of a window of the awning type comprising a plurality of sash or vents shown partly open and embodying my invention.

FIGURE 2 is a vertical sectional view on the enlarged scale on the line 22 of FIGURE 1, in the direction of the arrows, the sash being partly open.

FIGURE 3 is a vertical sectional view to the scale of FIGURE 2, but on the line 3-3 of FIGURE 5, in the direction of the arrows, the sash being closed and locked.

FIGURE 4 is a vertical sectional view on the line 44 of FIGURE 3, in the direction of the arrows.

FIGURE 5 is a horizontal sectional view to an enlarged scale, on the line 5-5 of FIGURE 3, in the direction of the arrows.

FIGURE 6 is a horizontal sectional view to the scale of FIGURE 5, on the line 66 of FIGURE 3, in the direction of the arrows.

FIGURE 7 is a fragmentary vertical sectional view on line 7-'7 of FIGURE 5, in the direction of the arrows, but to the scale of FIGURE 4, showing the sash in fully open position.

FIGURE 8 is a front elevational view of the window structure, as from the right of FIGURE 7, showing the sash in fully open position.

Referring to the drawings in detail, there is shown a window structure of the awning type, generally designated 10, comprising a window frame 11 the side elements of which are channel shaped in horizontal section, as viewed in FIGURE 5 for example. These channels, here designated 12, have bases 13 from which outwardly project a relatively wide outer web 14 terminating in an outwardly projecting flange 15 and a relatively narrow inner web 16 terminating in an inwardly projecting flange 17. The flange 17 may be provided'with an outwardly opening dove-tailed groove 18 adapted to receive the tongue portion of a flexible molding or weather stripping, which may be of the type illustrated in the Kleinknecht Patent No. 2,775,000, dated December 25, 1956.

Vertically mounted in each of the channel members 12 is a slide bar 19, which may be channel shaped in section as viewed in FIGURE 5, and be guided over flange or rib portions 21 projecting inwardly from the adjacent web 14 and which the flanges thereof embrace. Each slide bar 19 is thus mounted for up and down or reciprocating movement in its channel and carries at its lower end a sash bracket or hinge, member 22 for a window sash 23. It may carry thereabove a hinge member (or members) (not shown) for one (or more) sash 23'. The sash 23 is desirably for-med of metal and a pane of glass 24 is shown disposed between outstanding flanges 25 thereof. The hinge members 22 of each sash are connected tothe slide bar 19 as indicated at 20 for the lower sash, the connection for the upper sash 23' not being illustrated. Window sash 23 is connected to the window frame 11, and specifically to the side channels 12 thereof, 'by links 26, the inner lower end of each of which is pivoted to the adjacent channel 12, as indicated at 27, and the upper outer end of which is pivoted to a side member of the sash 23,

as indicated at 28. The window sash 23 is connected to the frame 11 above, but like, the sash 23.

Operation of the window sash 23 and 23, from a closed and locked position, illustrated in FIGURE 3, through the partly open positions illustrated in FIGURES 1 and 2, to the fully open position, illustrated in FIG- URE 7, and back to closed position, is effected by corresponding down and up movement of the slide bars 19 through the medium of links 29 pivotally connected at their upper ends, as indicated at 31, to the lower end positions of their slide bars 19, and their lower end portions pivotally connected to the outer ends of cranks 32. These cranks 32, one for each of the links 29, are fixed on and respectively extend from a shaft 33 which serves as a pivot therefor.

Suitable means are provided for operating one of the cranks 32 and, through the latter, the links 29 at opposite sides of the sash 23. The means in this instance comprises .a turnable operating handle 34 having a shaft 35 pivoted to the frame 11 and carrying thereon a worm 36 which meshes with a worm wheel or a toothed segment thereof 37, pivoted to the frame ll as indicated at '31). The segment 37 has a power arm or extension 38, the end portion of which is connected to a power link39, as by a pivot pin 41. The lower end of said power link 39 is connected to the adjacent crank 32, as by means of pivot pin 40. Thus it will be seen that operation of the handle 34 effects raising or lowering of the adjacent crank 32 and, through the connecting shaft 33, a similar movement of the other crank 32 takes place, operating the links 29 at each side of the sash 23 and effecting a corresponding up or down movement of the connected slide bars 19, to thereby raise or lower the pivoted upper ends of the sash hinge members and swing the sash 23 and Patented July 24, 1962' 23' about their links, and said links about their pivot pms.

The means for locking the sash 23 in the closed position illustrated in FIGURE 3, as well as the sash 23' thereabove if such is employed, as in the present embodiment, comprises a latch or a hook lever 42 for the lower sash and a corresponding latch or hook lever 4-2 for the upper sash 23, for respectively swinging down over and into latching engagement with studs 53 and 53, outstanding from the adjacent sides of the sash flanges 25 and 25. These hook levers are united by a link or actuating bar 43, the lower end of which is pivotally connected, as indicated at 44, to the lower hook lever 42, and the upper end (or if there is a sash above that designated 23', an intermediate portion) is pivotally connected, as indicated at 44, to the hook lever 42. The hook levers themselves are each pivoted adjacent their inner ends to the corresponding channel 12, as indicated at 45 for the lower hook lever, and 45 for the hook lever thereabove. This means that these hook levers move together as a unit; when one is up the other is up, and when one is down, the other is down.

The means for causing these levers to act in unison with the sash operating mechanism to automatically lock the sash when closed in the position in FIGURE 3, or release it to move to the position of FIGURES l and 2, or that of FIGURES 7 and 8, as the windows are opened, comprises a bell crank lever 46 which in the present embodiment is shown as generally triangular in side elevation, but which is effectively (and may be correspondingly shaped to have) a short portion or arm 47, pivotally connected to an intermediate portion of the actuating bar or link 43, as indicated at 48. The other corner or end of the long arm 49 of the bell crank lever 46 is, in turn, pivotally connected to a sleeve 51 which is freely slidable on the adjacent link 29, whereby swinging of said link during the operation of the window sash, causes the link to slide through said sleeve 51 and correspondingly rotate the bell crank lever 46 about its pin 52 which pivotally connects it to the adjacent frame channel 12.

It will thus be seen that as the cranks 32 start to swing out and down from the position of FIGURES 3 and 4, toward that of FIGURE 2, upon operation of the handle 34, there is at first practically no movement of the slide bars 19 for swinging open the sash 23 and 23' because of the initial dead center position of the links 29. However, this is the position of maximum raising movement for the actuating bar 43 by the short arm 47 of the bell crank lever 46 as it swings upon movement of its sleeve 51 along the adjacent link 29, so that the latches or hook levers 42 and 42' are quickly raised to release position, illustrated in FIGURE 2, prior to any appreciable raising of the window sash from the position of FIGURES 3 and 4. This unlatching is facilitated by the initial downward movement of the lower portions of the sash by virtue of the downward movement of the slide bars 19 as the cranks 32 swing counterclockwise, as viewed in FIGURES 2 and 3. It will be noted that there is only a relatively small further raising of the actuating bar 43 by said bell crank lever arm 47 after the cranks 32 move from the position of FIGURE 2 to that of FIGURE 7, that is, in the vicinity of the dead center position of said arm 47, as there is no need for moving the hook levers beyond the unlatching position, about as viewed in FIGURE 2.

The opposite effect occurs upon turning the cranks 32, from the position of FIGURE 7 through that of FIGURE 2 and back to that of FIGURE 3, to effect closing of the window sash. That is, the sash are closed, practically to the position of FIGURE 3, as the hook levers or latches 42 and 42' descend over the outstanding studs 53 and 53' on said sash 23 and 23', respectively, to thereby lock or hold shut said sash in the closed position.

Having now described the invention in detail in accordance with the requirements of the patent statutes,

those skilled in this art will have no difficulty in making changes and modifications in the individual parts or their relative assembly in order to meet specific requirements or conditions.
